The design of intelligent vehicle based on ultrasonic and infrared sensors
Abstract：With the progress of science and technology, the development and design of intelligentvehicle has been greatly developed, and the application of smart vehicle technology in life isbecoming more and more common. This design is based on the needs of the contemporarysociety, researchingthe intelligent vehicle’s function of tracking and bypassing obstacle. This smart caruses STC89C52 as the control chip;using the reflection type photoelectric detector RPR220 as black line tracking; infrared obstacle avoidance sensor as the obstacle avoiding sensor module;using the photoelectric sensor and speed encoder as the velocity measurement module. This paperintroduces theprocess of realizing intelligent vehicle tracking and obstacle avoiding function, from the beginning of the sensor scheme is discussed, after the introduction of the smartcar hardware, this paper introduced the smart car’sthe idea of program and process. The focus of this design is to achieve the function of tracking and bypassing obstacle, the design is completed whenthe final complete this task, we demonstrated the design ofbypassing obstacle can be achieved.
